IMPROVEMENT IN HORSE HAY-FORKS.

The Schedule referred to in these Letters Patent and making psx1: of thesame.

A l I To all 'whom it may conce/rn Y Be it known that I, J onsT S.YIxeEn, of lvlanchester township, in the county of York, and State ofPenne` sylvania, have invented a new and improved Hay-Fork; and Ldohereby declare that the following is a full, clear, and exactdescription ofthe construction and operation of the same, referencebeing had to the accompanying drawings, making a part ofthisspecification, in which- Fignre 1 is a perspectiveview- Figure 2 is aside elevation. The object of this invention is to provide for publicvuse a- 'hcrse hay-fork, having two pivoted jaws, so constructed andoperating that they can be readily opened and closed to rece-ive ordischarge the hay.

In the drawingsv A A represent the two jaws, pivoted at their upper endto a short, stout bolt, B, each of the jaws extending downward from thepivot B, in a straight line, to the point a, thence outward and slightlydownward, to the' point a, and thence downward, and curving slightlyinward tothe point a?, the extremity of the tines, and being serrated ats, on their inner side, near their lower extremity.

The jaws being thus constructed,'a plate, C or C', is fastened upon theupper sideof the inclined shoulder a, a of each. The two plates are ofnearly similar form, each having a lug, c, at its inner, and aprojection, c or c2, at its outer end, the projection c being simply arest for the lever, and the projection c2 being' an eye, through whichpasses the cord, hereinafter described.

To the lug upon plate C is pivoted a lever, D, and to that upon plateC', a link, E, the link passing around the jaws, just above the angle a,and being jointed tov the lever at e.

A cord, F, is fastened to the outer end of the lever,

and extends through the eye ci, and thence to a convenient point to beoperated by` the attendant.

A link, G, may be, attached to the upper extremity of the jaws, forconvenience in raising and loweringthe instrument by means of a tackle,and a short curved arm, fi, carrying a sleeve-roller, if thoughtnecessary,

may be fixed to the side ot suclrlink, as a guide for the`cord F, itsoperation being fully shown in Iig. 1.

In using the instrument, thetines are opened, by

throwing the lever ,river to the right, as seen in iig. 2,

and in that position they are thrust into the hay. The lever is thenthrown over to the left, as shown in fig. l, which brings them together,and causes them to grasp and hold securely the' hay that may beintercepted between them. The tines being held in this position, theinstrument is raised by the tackle.

It will be observed that when the lever is thrown over into the positionshown in iig. 1, it locks the tines together, the joint e coming belowthe fulcrum c, so that the expansive pressure ofthe hay against thetiiies only causes them to hold it the more firmly.

Having thus described my invention,

What Ik claim as new, and desire to secure by Let- .ters Patent, is-

The instrument above described, consisting .essen-. 5 tially of the jawsA A, made in the form describedthe plates G C', the link E, the .leverD, connected to the link at c, the cord F, the link G, the arm i, andthe Y pivot-bolt B, all constructed, arranged, and combined, so as tooperate together in the manner and for the purpose specified.
